RADIATOR.

Specification of Letters Patent.

To all fwwm it may concern:

Be it known that I, FREDERICK M. Orrrz, a sub]ect of the Emperor of Germany, re-

siding at Chicago, in the county of Cook and4 State of Illinois, have invented certain new and useful Improvements in Radiators, of which the following is a description.

My invention relates to means for cooling the circulating fluid employed to control the temperature ofgas engine cylinders orv other parts in motor vehicles and the like..

The object of my invention is to provide a simple,.stroi`1g and highly ecient device of the kind described, arranged to ploy the air as a medium for cooling the liquid in the radiator. i Y

To this end my invention consists in the novel construction, arrangement and combination of parts herein shown and described, and more particularly pointed out in the claims. Y'

In the accompanying drawings wherein like or similar reference characters indicate like or correspondingparts: Figure- 1 is a fr'oiit` elevation of my improved radiator. Figi '2, is an enlarged fragmentary section of thesametaken substantially on line 2 2 of Fig.y 5; Fig. 3 is an enlarged fragmentary section taken substantially on line 3-3 of Fig. 5. '.Fig. 4 is an enlarged end view of a part of, the cellular portion of my radiator.

Fig. 5 is a section taken substantially on line 5 5 of Fig. 2. Fig. 6 is a section taken substantially pn line 6-6 of Fig. 2. Fig. 7 is a perspective detail of the parts employed for forming a Section of my radiator the saine being in substantially their normal relation to each other but separated laterally to more: clearly show their form and eolistruction. Fig. 8 is a perspective View s imilar to Fig. 7 showing a slightly modified form of my device. Y

In the preferred construction shown -my device consists of-a suitable formed frame or casing comprising an inclosing band 1, providedfwith an inwardly extending marginal flange 2, at each edge the width of thev flanges 2 ybeing slightly greater at the top and bottom of the frame, as at 3 and 4, respectively, so as to form a pair of chambers or receptacles between theflanges.

Theradiatingor heat dissipating portion of my device consists of a plurality of conduits of suitable form extending betweenthe chambers 3 and 4 and adapted to permit a circulation of the water lor other cooling luidbetween the chambers. In the preferred construction shown `each conduit is substantially rectangular in cross section and curved longitudinally to form a series of semi-cylindrical arches. The adjacent conratenteu tray es, raie.

duits are arranged to coperate to form a n plurality of series of openings each extending from the front to the back of the radiatoi"2 each series comprising a vertical row of cylindrical openings alternating with a similar row of angular openings. In the preferred construction each tube consists of a plate 7 and a strip 8. rIhe plate 7 is of rectangular shape bent to form a series of evenly spaced semi-cylindrical` arches eX- tending transversely thereof and withv flanges 9 and 10 at its opposite edges. As showngthe ianges extend at substantially right angles to the body portion of the plateand the width of the flanges correspond to the desired thickness of the channels. The bases of the several arches are connected by a longitudinal portion 11, the.

width of which is approximately double the desired thickness of the channel. The strip 8 is also rectangular and formed to snugly fit between the flanges 9 and 10 and is bent to accurately correspond to the lateral configuration of the plate 7 when uniformly spaced therefrom. Suitable means are provided to gage the distance between the strip and plate. In the preferred construction a part 14 at each edge of the strip is o'set slightly from the body' portion and formed to accurately fit against the side of the plate. The shoulder 15 between the body portion of the strip and offset part'14 forms' substantially` the edge of the conduit and accurately corresponds in width to the width of the Hanges 9 and 10 upon the plate 7. If desired, also a slight depression 16 is formed intermediate the edges of the plate 8 .the depth of the depression corresponding to the width of the shoulder-15 so that when the plate and strip are \`in contact, the wall of the depressions 16 w-ilLengage the plate and thereby 'gaging the distance between the central portions of the plate and strip. When thus. constructed the strip is positioned between the flanges 9 and 10 and held in contact with the plate and the edges are united by solder, cement or other suitable material preferably filling 'the oilset por-p tion of the strip on both sides of the plate adapted to form a strong and fluid tight closure between them. i

In constructing my radiator a. plurality of the conduits above described, are brought into coperative relation with each other as shown in Figs, 2, 3, and 4 and the points of contact between the several conduits are permanently connected with solder or other suitable cement to firmly hold the several conduits in the desired relation to each other, each conduit is of sufficient width to snugly fit between the flanges 2 of the frame 1 and of sufficient length to extend across the opening between the parts 3 and 4. The con-4 tions 17 and 18 are provided at the upper and lower ends respectively of the side portion of the frame between the flanges 2 and extending from the wall 1 to the wall of the adjacent conduit. The partitions 17 and 18 are each soldered or otherwise securely fastened in position and arranged to prevent the cooling fluid from entering the space between the flanges 2 and the partitions.

v This portion of the frame serves as a convenient 'part for attaching the radiators to the frame of the vehicle thereby avoiding leaks incident to straining the radiator at its point of attachment to the vehicle.

In the form shown. in Fig. 8 the plate, strip and frame-are each formed substantially as hereinbefore described except that the offset portions of the strip are enti-rely Y omitted and the shoulders 15 are formed at the extreme edges of the strip and adapted to coperate with the flanges 9 and 10' to hold the members in their proper lateral relation to each other when assembling the device as well as to suitably space the members from each other and provide a sufficiently strong joint'bet'ween them.

Havi-ng thus described my improvement it is obvious that various immaterial modifications may be made in Amy device without departing from the spirit of my invention hence, I do not wish to be understood4 as limiting myself to the eXactform and construction shown. l

What I claim as new and desire to secure by Letters Patent is: 1. In a cellular radiator, a plurality of rectangular conduits each comprising a plate and asubstantially flat laterally projecting as flange formed at each edge of said plate,`in
